INTERNAL-COMBUSTION rREssnEE-rUivrP.

To all whom it may concern Be it known that 1, JO N A. MCINTYRE, citizen of the United States, residing at the city'and county of Denver and State of Colorado, have invented certain new and useful Improvements in Internal-Combustion Pressure-Pumps; and I .do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appcrtains to make and use the same, refcrencc beinghad to the accompanylng draws 'ings, and to the characters of reference marked. thereon, which form'a part of this My invention relates to in'iprovements in pumps in Wl11Ch lZl1(, water raising :force results from explosions in cylinders with which the pump is provided, these cylinders being supplied with an explosive mixture, tho-latter being ignited at properly timed intervals, whereby explosions alternately occur in, the two cylinders. Pistons working inthese cylinders are operated by a motor or engine of small capacity, being just suflicient to keep the cylinders in motion, the power for raising or pumping the water. being exerted by the aforesaid explosive force.

Provision is made for locking the pisagainst the recoil stress exerted by the explosions, whereby undue strain on the mechanism is avoided. Furthermore, provi- ...on is made for exhausting the burned products which pass with the explosive force into the chamber. or compartment" where the wateris acted upon and whereby'the pressure in this chamber after each explosion is atmospheric only, since said chamber is open to the atmosphere both for the admis sion' 01 the atmospheric air and for the exhaust of any burned gases which may have entered the chamber.

V The explosions occur in each cylinder before the piston therein has reached the head adjacent the explosion compartment. Gonsequently, an opportunity. is f given for which are trapped beyond-the outlet for the explosive force after the piston" passes said outlet. These remaining burned,prod ucte by reason o'f the grooved construction of the cylinder are allowed to pass to the opposite side or rear thereof, whereby they 1n ay escape to the atmosphere either through the outlet forthc xplosive force by Way f scavenging the cylinder of burned gases F1 Specification of Letters Patentj Pate ted Mar. 9, 1920.

the water chamber or at the opposite extremity of the cylinder which is open for the purpose. I Having briefly outlined my improvement I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof. In this drawing: 7

Let thenurneral 5 designate each of two cylinders which are mounted on a suitable bed or-foundation 6, each cylinder having a piston '7' .rnountedto reciprocate therein, the pistons being respectively secured to the oppos te extremiti s-0f, a conn.e cting;.r0

pendent contacts taken on the line 109 10,

or stem 8 which passes through stuffing boxes 9 with which the inner heads 10 of the cylinders are equipped. Each cylinder is provided. near its inner head with an in let 12 for the entrance of explosive mixture, 1

this mixture being introduced by way of a pipe 13 having an inwardly opening check valve 152 which unseat-s to permit the entrance of the explosivemixture and which seats as soon the explosion occurs in the compartment 15 of each cylinder.

These pistons are operated from a small motor or engine 16 which serves to rotate a shaft 17' provided with a worm 18 which operates a worm wheel 19 carrying a wrist pin 20 offset from its center sui'ficiently to give the necessary throw or travelto the pistons. This wrist pin is connected by means of a pitman 21 with a cross head 22 mounted in a suitable casing 23 and'connected means of an arm 2% with the piston rod 8 which is provided with two horizontally disposed a 111$ 25 whose outer extremities are provided with swinging pendents 26,

each having an insulating. cover 27 and an.

exposed contactQSintegralwith the memher 26 (Fig. 10), and forming a good couductor for the electric current.

The explosions in the two cylinders .occur in the compartments 15 or the compart ments adjacent the inner heads '10 of these cylinders. The two contacts 26 .are so ar-- ranged that their metal parts 28 are on their inner surfaces or the surfaces toward the center of the machine when the structure is in the position illustrated. in Fig. 1, in which this contact mechanism is shown, but on a very small scale. As the pistons move toward the right, the left hand contact 26 will strike a cooperating "contact 29, its metal part 28 engaging the same and closing a circuit by way of rod 8 tl'irough a spark plug 30, whereby an explosion occurs in the left hand cylinder 5v and at the right of the piston. Again, if the pistons move toward the left in the cylinders, the right hand contact 2-6 will engage with its metal part another cotiperating contact 29 whicl'i will close the circuit by way of rod 8 through aspark plug 81 and produce an explosion in the right hand cylinder at the left oi. the piston The pendent contacts 26 in Fig; i. are so arranged that'they engage the cooperating contacts 29 shortly after the pisstons within the cylinders have left the outer extremities or heads of the cylinders, who 'e by the explosion occurs with very little coinpression of the charge of the explosive mixture.

It will be understood that as either pie ton 7 travels tO WZLLCltl'IB outer extremity or head of the cylinder, a charge of explosive mixture is drawn. into the compartment 13 ot the cylinders. by virtue of the partial vacuum produced by such movement of the ing through the check valve controlled inlet 'pipe 13, then as the piston begins its inward movement it would immediately begin the compression of the gas charge; but I have found from experience that it is not necessary to compr the gas charge to any great extent or even at all in order to ob tain the necessary explosive force for water raising. Hence, as before stated, the pendent contacts 26 are so arranged with reference to the cooperating contacts 29 that the explosions will occur shortly after the respective pistons begin their return move ments, or their movement toward the inner heads of the cylinders.

Each cylinder is provided ncar'its inner head with an outlet port 32 for the explosive mixture, this port being normally closed by acheck valve 33 provided with a stem 34 which is surrounded by a spring -36 which engages a stop on one extremity while its opposite extremity bears against a tension nut 37 which is screwed into the outer extremity of a casing member 38, the latter being connected with a screwcap 39 which is screwed into the main casing 40 of the valve 83. This valve is held seated with sufficient force to maintain the port 32 clcsed'at all times except when the explosion occurs and then the valve is unseatcd to allow the explosive force to pass out of the cylinder and into a water chamber a1 by way of a conduit There are two at these conduits i2, one in conu'nunication with themain valve casing lO of each cylinder. These conduits l2 unite in a union 4 from which a single conduit it leads downwardly and communicates at its lower extremity with the chai'nber all. T his chain her is submerged either wholly or partly in thewater d5 of the ell 46 or of the stream or other source from which the pump is taking its supply. lhe chamber is provided at its lower extremity with an opening 17 which normally closed by a gravity check valve vertically movable on a stem 40, whereby the water within the chamber at].

will assume the same level as in the well or other source. As illustrated in the drawing, the chamber 4-1 is supported by the pipe or conduit member stat whose lower extremity secured thereto. It will be understoou, however, that any suitable means may be eniployed for supporting the chamber 41 within the source of supply.

The action, of the explosive force on the water in the chamber ll causes the same to rise within the funnel shaped lower extremity 50 of a stand pipe 51, the lower part 52 of theiunnel shaped member being cylindrical and having an opening 53 in its bottom which is norn ally closed by a check valve 5st which is v f ally slidable on a stem 55. As the explosion occurs, the water pressure opensthe check valve 54: and the water rises larly in operation, since the explosions oc-,

compartments 15 of cur alternately in the the two cylinders.

Attention is called to the fact that the chamber 41 is in communication withthe at-- which is connected with an oscillatory ari'u 62, the latter in turn being connected with the piston stem 8 about midway of the latter,

as shown at 63 (see Fig. 1)." A pin on the.

' piston stein enters a slot 64: in the arm 62, so that as the piston reclprocates the necessary iii) oscillatory movement is imparted to the arm to regulate the ports 59 with which the plate 58 is provided, theconstruction and arrange ment of the parts being such that the upper extremity of the pipe 56 isopen to theat-' mosphere at all times except when the explosions occur in the cylinders. At such times it is, of course, necessary in order that the explosive forcemay be utilized to the best advantage in raising the water through the stand pipe that any escape of such force" to the atmosphere is cut off. As soon, however, as the explosion occurs and has spent its force on the water in the chamber a1, the rotary valve 62 is shiftedto open the pipe 56 to the atmosphere, whereby any undue'pressure in the chamber 41 is relieved, the burned products of combustion which have entered said chamber being also allowed to escape to the atmosphere; Hence, asthe pressure within the chamber and the we'll or other source of supply is the same, namely, atmospheric, the water within the chamber will resume its normal level in time for the next explosion. Y i After the explosion has occurred in either cylinder, the piston moves inwardly toward the opposite head and scavenges the burned products of combustion which are forced out through the port 32, until the piston closes or passes this port, after which the re mainderof these gases will escape through reach beyond the piston when the latter is at its innermost limit of movement, so that these gases may pass into the compartment beyond "the piston and escape either through the port'32 or at the outer extremity of the cylinder Whose head '68 may be'provided with openings 168 for the purpose. In fact,

the outer extremities of the cylinders may it desired be entirely open, or if they are closed, the piston stenimay be hollow and 7 open at its extremities to prevent any com press On between the outer heads of the whichoccur when the pistons are traveling inwardly, I provide means for positively locking the pistons againstreturn movement at the instant any explosion occurs. This inechanismconsists of a couple of links 69 which are pivotally connected, as shown at 7 O, with collars 71 mounted on the piston stem between the two cylinders. These links cooperate with dogs 72 which are pivotally mounted, as shown. at 78, incavities 7 1 formed in the upper portion 75 of the base or foundation of the structure, this part 75 being mounted on the main base member 6. Each dog 72 is so arranged that when the corresponding piston is traveling outwardly in its cylinder the lower extremity of Y the link 69 engages a projection 75 on the dog and moves the latter to the dotted line position (see Fig. 3), whereby the link moves idly. However, when the piston is arrangement prevents any strain upon the piston operating mechanism as will be readily understood. The collars 71 are adjustable 'on the piston rod in order that they maybe so positioned as to accommodate varis 'ations with reference to the inward travel of the pistons'before the explosions occur for. varying the degree of compression. As illustrated in the drawing, provision is made for water cooling the cylinders, ack

ets 78 being provided which are in communication with inlet and outlet pipes 79 and 80. From the foregoing description the use and operation of my improved pump will 1 p be readily understood. The pistons are re 7 I ciprocated through the medium of the motor 16, whereby the shaft 17 is rotated and operates the crank wheel 19 through the medium of the worm gearing connection'heretofore explained. This'wheel. is connected with the piston stem to receiprocate the pistons. .When either piston has reached its inward limit of movement in one cylinder and'begms its outward travel, it begins to draw a charge of explosive mixtureinto the compartment 15 thereof- At the same time the other piston begins its inward travel,

during which travel the explosion occurs and which may be so timed that the explosive mixture is compressed more or less Within the cylinder. The construction, as

arranged, as heretofore explained, assumes that the explosion will occur soon after the piston has commenced its inward travel.

This may be varied, however, in order that the explosive mixture within the cylinder may be considerably compressed before the explosive mixture is ignited. As soon as any explosion occurs, vthe explosive force through the medium of the connections here toiore explained acts on the water in the chamber 41 and causes the same to rise through the stand. pipe 51 in a continuous stream, since the explosions which occur alternately in the two cylinders have sui'licient frequency to produce this result.

In operation the pistons move continuously forward during compression, explosion and scavaging, The lock mechanism, 69, 71, 77, is used only to relieve excessive strain from the driving parts, 1'7, 18, 19 and 21, at the instant of explosion in case these parts are not deemed strong enough in themselves to withstand the strain. But t 1e movement of thepistons is still continuously forward.
